The wig form and attached wig or hair piece may be covered with a hairnet and may be placed in a box for sale to a consumer or for storage by the consumer after sale. Embodiments allow the display before sale and convenient storage of wigs and hair pieces by the consumer while preserving the curl of the hair.

Abstract: A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.

Abstract: The invention relates generally to a nebulizer, for example, of ultrasonic nebulizer (30) having a bowl shaped container (12) and a tubular energy transmitter in the form of acoustic transmitter pipe (34). One end of the acoustic transmitter pipe (34) is immersed in the liquid (14) of the container (12). The bowl shaped ultrasonic transducer (16) is operatively coupled to the bowl shaped container (12) for transmission of ultrasonic energy to the liquid (14) and acoustic transmitter pipe (34). Absorption of transmitted energy by the liquid (14) forces the liquid (14) toward an upper end of the acoustic transmitter pipe (34) where it is nebulized in the form of an aerosol. The invention also relates generally to a device and method for delivering a substance in an aerosol form into a cellular organism, and a hand held device for delivering a substance to a cellular organism.

Abstract: The method and system are for sealing/unsealing (regulating) airway leaks occurring between the ventilator circuit and respiratory airways during lung ventilatory support in response to myoelectrical activity of diaphragm. Myolectrical activity of a patient's respiratory-related muscle is sensed to detect respiratory effort, and to produce a myoelectrical signal representative of the sensed muscle myoelectrical activity. Respiratory flow and pressure can also be measured to produce respective respiratory pressure and respiratory flow signals. A logic trigger sealing/unsealing of airway leaks in relation to the myoelectrical signal, respiratory flow signal and/or respiratory pressure signal to assist respiration of the patient. The amplitude of the myoelectrical signal is compared to a given threshold, and airway leaks are sealed when the amplitude of the myoelectrical signal is higher than this threshold.

Abstract: A dry powder inhaler has a dispersion chamber containing beads. A dose of dry powder is released into the chamber, or into an inlet tangentially joining into the chamber. As the patient inhales on a nosepiece or mouthpiece, air moves circularly through the dispersion chamber to drive the beads. The beads roll, bounce, and collide repeatedly with the drug particles on the chamber surfaces or on the beads. The smaller active drug particles are separated from larger carrier particles and from each other, and a powder aerosol is created and inhaled by the patient. The beads are preferably lightweight, so that they can be rapidly accelerated and moved, even with nominal inspiration. The flow resistance of the inhaler is also reduced via the beads, allowing greater airflow and powder dispersion, without any increased effort by the patient.
